How Crushers Work: The Operation of an Impact Crusher MINING

Optimal Energy Control Modelling of a Vertical Shaft Impact

This paper presents an optimal control model to improve the operation efficiency of a vertical shaft impact (VSI) crushing process. The optimal control model takes the energy cost as the performance index to be minimized by accounting for the timeofuse (TOU) tariff. The control variables in the developed model are the belt&nbsp

Load and wear experiments on the impact hammer of a vertical shaft

The wear distribution of the impact hammer was measured by shape morphology according to relative impact crushers. The results demonstrated that the real measurements of wear distribution on the impact hammer were similar to simulated load distribution measurements on the same surface. The study of load&nbsp
